摘要： The invention relates to a control device (2) with a time measuring function which measures a turned-off time of an ignition switch (3) with a low consumption current and high accuracy at a level adapted for a demand from the controlling side, as well as a turned-on time of the ignition switch (3). The control device (2) also measures an accumulative turned-on time of the ignition switch (3). The control device (2) comprises a battery (1), a microcomputer (7) for computing a control variable to control a control target, a time measuring unit (10), a clock source (12) for the microcomputer (7), a clock source (5) for the time measuring unit (10), and a unit for changing over operation of the time measuring unit (10) depending on an intended use. The time measuring unit (10) operates regardless of run/stop of the microcomputer (7).
